.To all eli/"icm t may 00:10am.'

Be it known that l, fla s H. Teenies/N, a citizen ot the United States, residin. l'reiiton. l/lercer County, New dersey, have invented oei .un improvements in Dyeing fachines, ot which the 'tollowinb' is aspecication.

My invention relates to certain improvements in dyeing machines oi: the type in which the hanlrs ot yarn are suspended in a vat and in nwhich a. circulating means is located at one end the vat so that the liquor will be circulated through the vat in either direction.

rlhis application is a4 division of the application for patent tiled by ine on the 23rd day of February, 1918, Seria-lilla 263,856, which resulted in a patent granted on the 25th day of Uctober, 1921, No. 1,395,185.

rEhe object of my invention is to improve the construction ot the means tor suspending the hanlrs oif yarn in the vat so as to prevent the straining oit the sticks and to provide means whereby the rods, which are located at the top and bottom ot the vat, can be readily removed and replaced when breal-- age occurs.

ln the accompanying` drawings:

Fig. 1 is ar longitudinal sectional view oi a dyeingmachine illustrating my invention;

Fig. 2 is a, sectional view on the line 2*-2, Fig. 1;

Fig. 3 is asectional view, similar to Figi. 2, illustrating the method oit removing the sticks; and

Fig. 4 is a sectional view on the line sea, Fig. 1.

Referring to the drawings, 1 is the vat. it one end of the vat is a circulating device consisting' ot a power driven shatt 2 having a` propeller 3. This propeller is located in a circulating passage 4e separated 'trom the main body 5 ot the vat by a partition 6, which stops short of' the top and bottoni et the vat so that the liquor can circulate through the body oit the vat and the circulating passages.

'lhe propeller is driven by power mechanism applied to the shaft 7 mounted on a suitable frame 8. lt will be understood that other circulating means may be used without departing from the essential features of the invention.

ln the bottom of the vat is a grating con- Seral No. 263,856.

Serial No. 498,852.

Bivded and. this application filed sis-ting oi side bars 9 and cross bars 10. The side bars are made in halves and the sockets t' yhe cross bars are termed in these side bars, one-halt in the lower section and the other halt in the upper secti The cross bars do not extend through the side bars, but merely rest in the sockets so that when the bolts 11 are in position they secure the two parts ot the side bars together and clamp the ends oit the cross bars, as shown in Li. The cross bars are preierabljv in a line with the lower edge oi the partition 6 and torna a bottom channel through which the liquor can iow freely to and from the circulating passage e.

12 is a supporting 'trame tor the hanls ot yarn. This trame consists, in the present instance, of two longitudinal side beams 13 and a cent-ral beam 14:. These beams are connected together by cross beams 15 provided with eyes 16, which are engaged by the littin,y tackle when it is desired to litt the traine, with the hanlrs oi yarn thereon., into or out ot position in the vat. There are a series ot periiorations 17, which extend through the side beams 1 8 and a series of perforations 18 in the central beam 14. Vl`hese latter peri'orations do not extend through the beam7 Fig. 3.

ll`he yarn sticks 19 are located in these perfor-ations, one series of sticks being' on one side oiV the center beam and the other series beingon the opposite side. By providing,l a central beam, as shown, the sticks need not be so long as usual, and, consequently, they do not and become accidentally detached "from the supporting` traine, and are not warped out of position. Furthermore, they carry a fewer number oi sticks than heretolfore and are more readily handled by the operator than when long sticks are used.

Directly above the yarn carvyingsticks is a grating, similar to the one at the bottoni oft the vat. consisting oi a serios ot wooden bars 20. These bars are spaced a given distance apart and are clamped under the beams 18 and lei. by hars 21. 1lb-ese cross bars are short7 one set extending on one side of the central beam and the other on 'the opposite side thereof. They do not entend througl the beams, 1out merely rest in the sockets formed in the beams., and the bars so that when it is desired to replace one ot' the bars,

on account of breakage, all that is necessary is to loosen one of the side clamping bars to remove the broken cross bar and to place a new bar in its place.

Carried by the supporting 'rame is al cover 22 for closing the vat during the process of dyeing. rlhis cover has two hinged portions, one at each side, so that access can be readily had to the interior ot the vat to inspect the circulation. The remainder of the cover is made of a series of sections which can be removed, il found desirable.

rlhe operation is as follows: The dye liquor is placed in the vat and the circulating means is set in motion so as to circulate the liquor in the vat. Steam is added through the pipes 23 in order to bring the liquor to. the proper temperature. 'lhe particular color of dye is also added until it isV thoroughly impregnated with the dye liquor. The hanks oi yarn are then placed on the sticks and the sticks are located inthe frame, which is supported from an overhead trolley beam and when the liquor is in the proper condition to die the material, the yarn frame is swung over the vat and lowered into it so that the hanks of yarn will be submerged in the liquor.

On each inner wall of the vat are located bars 24, which come in close contact with the side beams of the supporting trame for the yarn and close the space between the side beams and the side of the vat in order to prevent the circulation of the dye liquor at this point and to insure all of the liquor being circulated through the hanks of yarn. The circulating means can be reversed so as to circulate the dye liquor in either direction through the yarn. One i'orm of circulating means is fully disclosed in Patents No. 661,343, Nov. e, ieee, and No. 1,395,165, oetober 25, 1921.

l claim:

l. The combination in a dyeing machine, of a vat; means for circulating the dye liquor therein; a supporting frame for the yarn consisting ot three longitudinal beams, two ot the beams beingperforated for the sticks on which the yarn is suspended, the central beam having recesses at each side for the yarn sticks; and two series ot sticks, one located at one side of the center beam and the other located at the opposite side thereof.

2. The combination in a dyeing machine, of a vat; means for circulating dye liquor in the vat; a supporting trame consisting of two longitudinal beams and sticks on which the yarn is suspended, said trame bein-g located in the upper portion of the vat; and means, on the inner walls of the vat, for preventing the circulation of liquor between the side beams oi.' the supporting frame and the walls of the vat.

3. The combination of a vat; means for circulating liquor in the vat.; and a yarn supporting trame mounted in the vat and having its longitudinal members comparatively close tov the side walls of the vat, said vat having longitudinal. bars extending under the sides oft the frame so as to prevent the circulation of liquor between the supporting iframe and the side oiZ the vat.
